Bieber Fever

Justin Bieber spent Thursday morning with Mariah Carey, filming a music video and ignoring the allegations of another Mariah: the 20-year-old woman who filed a paternity suit against the teen star.

Lawyers for Mariah Yeater, the fan who claims she and Bieber conceived a child during bathroom-stall relations last year, told Radar there is “credible evidence that bad credit loans [the teen star] is in fact the father of her baby.” Said evidence will be revealed in court this December.

Bieber and his team have called her claims “malicious, defamatory, and demonstrably false,” which is about as firm as a denial can be.

So what could Yeater’s “credible evidence” be, if it indeed exists? Was the baby born with Bieber’s signature haircut? A Canadian accent? Celebritology asked two law professors for guidance.

“‘Credible evidence’ likely refers to ‘circumstantial evidence’ tending to show (or even establishing) that the putative or alleged father had sexual relations with the unsecured loans mother at a point in time close to the date of conception,” Catherine J. Ross, a George Washington University law professor, explained in an e-mail. “This only means that he would be a possible candidate for paternity, and could justify a court order to subject himself to DNA testing.”
